The different stages of dressing of stones are: 1. Sizing: It is the process of inducing the irregular blocks to the desired dimensions by removing extra portions. It is done with the help of hand hammers and chisels. 2. Quarry mining Britannica,The products of dimension stone quarries are prismatic blocks of rock such as marble, granite, limestone, sandstone, and slate. After cutting and polishing, these materials are used in the primary construction of buildings and monuments and also for decorative facing materials applied to the exterior and interior of buildings.

Quarries are of two different types, the pit quarry and the bank quarry. The pit quarry is one in which the stone is extracted from below the general level of the surrounding country, and, as a rule, the stone is elevated to the crushing and treatment plant on the surface. Some operations in limestone and granite are of this type.
